I am looking to see what people with experience and knowledge think about the suspension upgrades I was thinking about.

I was thinking about:

J&M Adjustable Caster Camber
Whiteline Bumpsteer Kit
Whiteline Heavy Duty Adjustable Front Sway Bar
Whiteline Heavy Duty Adjustable Rear Sway Bar
Whiteline Complete Watts Link Rear Suspension
Whiteline Rear Lower Control Arm Relocation Brackets
Whiteline Adjustable Rear Lower Control Arms
Whiteline Adjustable Rear Upper Control Arm w/ Mount
Steeda Sport Springs - Coupe (11-14 V6)
KONI yellow Adjustable Shock & Strut Kit

which totals $3200

I was on the fence about the Eibach pro kit.

I daily drive my car and Autocross about once a month. The Eibach pro kit is cheaper but doesn't have a watts link which I heard great things about.

I am looking for something that not only gives me a lower stance but performs.
